The beginning of the Senju and Uchiha, was the start of a never ending war. The two brothers coexisted in the Naruto world from generation to generations, transmigrating to different beings.
Ever since, the Uchiha Clan Massacre, the only Uchiha who was meant to live was Sasuke. The Senju Clan disappeared way before the massacre only to leaves Tsunade and like other people's theory, Minato.
For Tsunade case, her father might not even be a Senju, so she may not be pure. (No facts whether Indra or Ashura will transmigrate to females) For Ashura case, there haven't been a female who have unlock the Sharingan (Besides the flashback).
For Obito, since Madara was still alive in his time, it is safe to said that Indra was still transmigrated in Madara, thus Obito did not inherit that will.
Minato was most likely a Senju like most people said which leaves Naruto being the last Senju.
Conclusion
When Indra and Ashura's soul are diminished, is when that hatred will ends. So Naruto and Sasuke will have a deathmatch to finish off what Indra and Ashura left off.
It parallels the meaning of the start and end.
